Title: Semiconductor memory
Inventor: ONO CHIKAU
IPC: G11C29/00
Filed: 2001-01-19
Abstract: PROBLEM TO BE SOLVED: To shorten the access time of a semiconductor memory having a redundant circuit for relieving the defect of a memory cell area. SOLUTION: A redundant information area which has a memory cell storing relief information indicating the location of a defective memory cell is arranged near at least either of a word driver or a plate driver relative to a memory cell area and a redundant memory cell area. For this reason, the memory cell of the redundant information area operates quickly compared with the memory cells of the memory cell area and the redundant memory cell area.
